大家好，我这边用3个华硕路由组AIMESH，网络拓扑如下：
问题是，自从3台开始组aimesh，就会每隔段时间出现网速奇慢（有线无线都是），然后主路由直接显示联机中断的情况。重启主路由有时候能修复，有时修复不了。
一般我就采取几种方式，一个是只重启主路由，一个是主从路由都重启，一个是重启交换机gs108. 一般其中会有一种方式可以临时解决问题。但是没有根本解决。使用的是有线回程。
PS：这段时间观察有时候还会有类似情况，比如从视频网站下载视频，如果手机直连主路由，网速没问题，如果手机连接的是从路由，网速会直接掉到，每个视频1M/s，暂停下载，连到主路由，网速恢复。（有时候是限制5M/s）。Qos之类的都没有开启。重启交换机108可临时解决。
最近一次是周六（11.15）早上8点发现的断网，具体断网时间不确定，发现断网后，重启了主路由，但是好像还是有问题，我就重启了交换机，问题得到临时解决。
请各位大佬，帮忙看看是什么原因，非常感谢。
syslog:
日志中有很多类似的日志行，我看的不是太懂，就感觉总有重连。

然后出现，一直持续：

然后8点我发现断网，进行路由器重启
